sweetpea86 writes: A Scottish Labour MP has been forced to step down as his party's “Twitter tsar,” after posting a video on his blog portraying Scottish National Party leader Alex Salmond as Adolf Hitler. Tom Harris, who stood for election as Scottish party leader last year, used footage taken from the film Downfall in a spoof video posted on his official website on Saturday. Harris replaced the English subtitles from the film with his own captions, poking fun at Salmond's secrecy over a referendum on Scottish independence.
